are present in a wide range of habitats, including freshwater, marine, and terrestrial locations, as well as extreme environments such as thermal springs.

A 2022 study first investigated PHB formation in Leptolyngbya sp.

Due to the high carbon storage capacity and poly(3-hydroxybutyrate) (PHB) formation, Leptolyngbya sp.

Further studies have demonstrated that Leptolyngbya possesses a balanced ratio of intracellular composition and high lipid content, and is therefore a suitable host for potential large-scale applications .

Future work will focus on upscaling to a technical scale and monitoring the formation by LipidGreen2-based fluorometry.
